- Abstract: Mycotic thoracic aortic aneurysm (MTAA) is a disease that is difficult to treat and often lethal. Open repair has high morbidity and mortality risks; additionally, thoracic endovascular aneurysm repair (TEVAR) often requires innovative techniques.We report the use of an innominate artery chimney endovascular aneurysm repair (ChEVAR) with carotid-carotid and carotid-left subclavian artery bypass for a time-sensitive Salmonella-related MTAA. A symptomatic type 1a endoleak was discovered and promptly and successfully treated. This report shows that the use of innominate artery ChEVAR to treat MTAA is feasible and safe, although the procedure is rarely performed, even in large series. We hypothesize that prophylactic gutter embolization is a feasible option in view of the high endoleak risks in such cases, although further evidence is required to support this.
